OK, so 'recent' assembly has already been done - not surprising.
We had a new assembler for the 9830 and figured it would be minor to (back-)convert it for
the 21xx. It hasn't been as straightforward as anticipated however, due to the
vagaries of the original HP assembler syntax.

I've actually extracted (an almost complete) machine code / binary image from the
assembly output listings you provided on bitsavers, but it's more interesting to
fulfil a complete assembly from the source, so we're waiting for that before trying to
load & run.
I have a cross assembler for the 21xx written in 'C' (I
didn't write it) but I don't recall where I got it from. :-( It produces an
absolute binary image that is suitable for loading using the binary loader. > With

Aside from blinkenlight programs, in the not-to-distant future there should be a
stand-alone version of HP BASIC available. A friend and I are working on assembling it
from source. (There are probably old binaries out there somewhere but I haven't
obtained one).
I have the binary tape image for HP BASIC somewhere other than in the core of my
HP2116. The source is up on bitsavers scanned (and OCR'd) from a listing that I have
had since 1971. There should be the BASIC tape images on bitsavers.
There are no binaries in the directory with the BASIC source, however it appears the
Moffat archive is now on bitsavers and there appears to be a binary there for a version of
the interpreter and PBS, along with lots of other early stuff to investigate.
I had found the Moffat pages years ago when they were at his own site, before they were on
bitsavers, but as I recall the binaries did not download transparently at that time,
that's why I was looking at assembling the source at this time.
(Your) source for BASIC is in the 'pdf' section of bitsavers, beside the hardware
manuals:
http://bitsavers.trailing-edge.com/pdf/hp/2116/BASIC_Jan70/
while the Moffat stuff with binaries is over in the 'software' section:
http://bitsavers.trailing-edge.com/bits/HP/paperTapes/JeffM/
I don't know what the story is with the Moffat stuff however, a lot of the file links
are dead.
Perhaps Al can comment.

fair number of HP paper tapes but I haven't yet had the time to check them against
what's on bitsavers to see if I have anything that isn't already there.

I'm a little limited as my 2116 currently has only 8KW memory.
